Scalar and Vector Forces

Question 1

A vector quantity has:

Answer 1

Magnitude and direction

Question 2

A scalar quantity has

Answer 2

Only magnitude (no direction)

Question 3

What are examples of vector quantities

Answer 3

• Force
• Velocity
• Displacement
• Acceleration
• momentum

Question 4

What are examples of Scalar quantites

Answer 4

• Speed
• Distance
• Mass
• Temperature
• Time

Question 5

In arrow diagrams the size/length of the arrow represents what

Answer 5

The magnitude of the force (in vectors)

Question 6

In arrow diagrams the direction of the arrow represents what

Answer 6

The direction of the force

Question 7

If two objects are travelling at the same speed in different directions what is the comparison of their speed and velocity

Answer 7

Speed: Speed is a scalar quantity, Therefore it only takes into account magnitude and not direction. Therefore both objects are travelling at the same speed even if they are going in different directions

Velocity: Velocity is a vector quantity. Therefore it takes into account both magnitude and direction. Therefore although both objects are travelling at the same speed they will have different velocities due to the fact they are going in different directions
